The Haber process uses a pressure of about 200 atmospheres.
N2(g)+3H2(g)⇌2NH3(g) \mathrm{N_{2}(g) + 3H_{2}(g) \rightleftharpoons 2NH_{3}(g)} N2(g)+3H2(g)⇌2NH3(g)Statement 1: A higher pressure would decrease the rate of reaction.
Statement 2: A higher pressure would increase the equilibrium yield of ammonia.
Statement 3: A higher pressure would need stronger, more expensive equipment and more energy.
